2013 SRT Viper

THE American Supercar is back and its back in a big way. The SRT Viper has made its triumphant return with its trademark 8.4 liter V10 which now packs 640 horsepower and 600 lb-ft of torque. No “flappy-paddle” gear box here, the new Viper will pack a proper but also new and improved six-speed, Tremec TR6060 close-ratio transmission that comes complete with a new aluminum housing, a lighter flywheel, and a self-adjusting twin-disk clutch.
